Popis: Activated carbon was successfully generated from the mixture of corn cob and petai hull which served as adsorbents for Pb (II) ion removal at an aqueous solution. The activation was done using KOH at 800°C carbonization temperature. Synthetic waste used in the various concentration of 100, 200, 300, 400 and 500 ppm. The adsorption process was carried out at 30 minutes, the ratio of adsorbent mass was grouped as B (1:3 corn cobnative activated carbon/petai hullnative activated carbon), C (1:1 corn cobnative activated carbon/petai hullnative activated carbon), D (3:1, corn cobnative activated carbon/petai hullnative activated carbon), and H (1:1, corn cobmodifiedactivated carbon/petai hullmodifiedactivated carbon). The results showed that the highest adsorption capacity was found in H adsorbent that was 2,368 mg/g at concentration 300 ppm. Dubinin model fit the adsorption isotherms of B, C, D, and H.
